The invention discloses a method and a device for establishing TE tunnel, the method comprises: a routing device and routing device between adjacent each receiving link state message, the link state contained in a message for RSVP-TE field configuration attribute identifies the link; the routing device according to the link state message collect link state information in MPLS network and the formation of TEDB; the equipment running CSPF routing algorithm, select the link configuration RSVP-TE protocol in the TEDB; the router TE tunnel is established according to the selected link. In the invention, a TE tunnel can still be normally established in the presence of an equivalent link in an MPLS network.
